13.1.3. Using a Driver Image During Installation
If you need to use a driver image, such as during a PCMCIA device or NFS installation, the installation program prompts you to insert the driver (as a diskette, CD-ROM, or file name) when it is needed.
However, there are some cases where you must specifically tell the Red Hat Enterprise Linux installation program to load that driver diskette and use it during the installation process.
The Red Hat Enterprise Linux installation program asks you to insert the driver diskette. Once the driver diskette is read by the installation program, it can apply those drivers to hardware discovered on your system later in the installation process.
